(Cl. 215-11)ABSTRACT OF THE DISCLOSURE A nursing unit having a first nipple held toa bottle by a first member threadably secured to the bottle. A secondnipple, encompassing the first nipple, is held to the first member by asecond member threadably secured to the first member.

This invention pertains to child nursing equipment, and moreparticularly to nipples comprising an improved nursing unit generallydescribed and shown in US. Patent 3,070,249 by Sehrwald, forNippleglove.

These and other objectives of the present invention will be understoodfrom the following description taken with reference to the attacheddrawing in which:

FIGURE 1 is a diagrammatic cross sectional view of the improved nursingunit in accordance with this invention.

FIGURE 2 is a diagrammatic cross sectional view of an improveddouble-sided screwtop 70, in accordance with this invention.

FIGURE 2 shows a double-sided screwtop 70. Here specific indentationsare provided in two areas: on the inner side 70a, for screw-grip withthe bottle 20. On the outside 70b, for screw-grip with the secondscrewtop 80. This double-sided screwtop terminates with a winglikestructure 700, to embrace the bottle firmly with its inner 3,401,813Patented Sept. 17, 1968 surface and to provide on its outer surfacegentle elevations for firm finger-grip.

Referring to materials used: the screwtop 70 is made of a suitableflexible material such as rubber, plastic, etc.

As seen in FIGURE 1, the nippleglove nursing unit does include themodified screwtop 70, the sleeve 10, the nipple 60, the second screwtop80, and the bottle 20.

The use of the modified screwtop 70, invented for the double-layerednurser provides several important advantages: (1) To secure a space ofspecific dimensions C, between sleeve 10, and nipple 60. (2) Screwtotp80 is screwed against screwtop 70, in a clockor counter-clock fashion.(3) To hold sleeve 10 firmly at a specific distance from nipple 60.

I claim:
